The Tea Research laboratory has developed expertise for analysing thousands of black and green tea (Camellis sinensis)samples for the tea industries in South Africa, Zimbabwe, Malawi and Kenya.
Our reputation has spread far and wide and we have analysed Guayusa tea (Illex guayusa) from Peru that is sold in USA as Runa tea.
We have analysed roots and leaves from African geranium (Pellargonium sidoides) sold as Linctagon in South Africa and Umckaluabo in the EU and USA.
We have established all the ISO methods relevant to tea and include total polyphenols by the Folin Ciocalteu reagent and individual flavonoids by UPLC.
